UNITED STATES SAMUEL WALKER, OF LILLE, FRANCE FLYEB SPINNING FRAME.

Application filed November 30, 1926, Serial No. 151,767, and in France October 20, 1828.

The present invention has for its object a device for removing rapidly and simultaneously all the full bobbins and replacing these bobbins by empty tubes, also rapidly and simultaneously, whichfldevice is,

adapted for use in all h or spinning frames in which the spindle ant the fiyer forms one body and is driven fromthe top, and more particularly in dry or wet spinning frames, doubling frames and machines and spinning frames for hemp, flax, jute and other textile materials.

This device, which may be actuated by hand, by semi-automatic means or automatic means, is oft-he so-called vertical type, that is to sayit is of the type in which the full bobbins and the empty tubes are displaced in a vertical plane by the move ment of the rise and tall meclianisni parallel to the vertical plane. n

The invention consists 1n the comb1nalion of means provided in the spindle plate tubes in place upon the spindle plate while tl'iey are being filled and for disen aging them when the bobbins are complete and accessory means for actuating by hand, in a semi-automatic or automatic manner, the various operations for points of the spindles from their footsteps as well for disengaging the tubes with their brake ropes or other e uivalent'braking means, for receiving the full bobbins removed, for cutting the thread of the full bobbins, etc. n

rtccording to one practical embodiment of the invention the means for allowing the lull bobbins to fall vertically are obtained by for-hiring sufficiently large apertures in the spindle plate to allow the passage of empty or fut tubes, the means for moving the empty tubes vertically upwards and carrying them through the apertures and above the plane of the spindle plate consist in rori ing below the said spindle plate a rail or plate carrying the replacement tubes and having'a vetrical motion and the means for retaining the tubes upon the spindle plate while thcyare being filled and for liberating the completed bobbins and allowing them to fallthrough the spindle platecondisengaging the sist in an intermediate plate resting upon the spindle plate, upon which intermediate plate are carried the tubes, the saidplate being adapted to make a longitudinahtransverse or other movement upon the said spindle plate and comprising suficiently large apertures to allowthc passage of the empty form of the device according to the invention is hereinafter described by way of example and is illustrated diagrammatically in the accompanying drawing, the princi a1 means mentioned above being employe in this form of the invention.

2) of dimensions larger than the diameter of a full bobbin. The centres of the apertures coincide with the axes of the spindles 3 to which they correspond in number.

The upper face of this perforated spindle plate 10 comprises in this form of the de- .vice a wide central longitudinal groove 12 in spaces separating each aperture 14 themselves comprising small apertures 15 the centres of which coincide with the axes of the spindles so as to serve as footsteps or thrust bearings for their points when the whole arrangement is in a working position.

The manipulation of the plate 13 for putting it' into a working position (Fig. 41) or V for bringing it into position for the removal of the bobbins (Fig. 5) is effected in this example by hand from the end of the frame, by means of a control level- 16 which enables V the said plate 13 to be made to slide along the slideway 12 in the spindle plate 10.

In order 'to permit the grooved bases 17 of the tubes 18, when they are slipped on to the spindle 3, to be engaged with ordisen gaged all at the same time, from their brake rope 19 which is weighted at 20, each of these ropes, which is connected at one end to the inner edge of: the spindle plate 10 passes over the notched edge of a bar 21 mounted parallel to the outer edge of the spindle plate along which it is adapted to slide in such a way that it can be moved to and he by hand by means of a controlling member, such as a lever 22 mounted at the end of the frame near the control level 16 provided for the plate 13, the eflect of which is to permit,

when the tubes are in placeupon the spindle plate, either all the brake ropes 19 to be brought simultaneously into contact with the grooves 17 of the tubes .(Fig. 4) or to disengage them from these grooves (Fig. 5) when the bobbins are completed and have to fallthrough the plate spindle 10.

At the end of the frame on the side of which are placed the control levers 16, and

22 is disposed a hand wheel actuating order to be able to disengage the points of the spindles 3 from the bearings or footsteps 15 in the sliding plate 13 and thus enable the latter to be displaced in order to allow the bobbin 18 to fall and the renewal tubes to rise through the spindle plate 10.

On a lower vertical plane, parallel to the plane of the rise and fall carriage 6, are mounted, upon similar guides, other carriages 26 comprising arms 27 supporting a rail or plate 28 arranged parallel beneath the spindle plate 10, the said rail being provided with spindle'heads 29 of small heightcorresponding in number to the spindles 3 and situated in alignment with the axes of the latter, the said heads 29 receiving the bases of the replacement empty tubes 18 the grooved bases of which rest upon cylindrical bases 30 of smaller diameter than that of the bases 17 of the tubes and adapted to serve, when the carriages 26 have been raised, as a means for bringing the said tubes on to the spindles 3 above the plane of the spindle plate 10 in order to permit the said replacement tubes to be placed upon the spindle plate 10 and subsequently retained by the plate 13 during the descent of the said carriages 26 with their rail 28. I

The rise and descent of the carriage 26 is obtained in thisenaniple by hand, in a similar manner to the additional downward movement of the carriage (3, by means of a hand wheel placed near the other control members and keyed upon a longitudinal shaft 31 carrying pinions 32 engaging with racks 33.

In order to prevent the full bobbins 18 when they are expelledvertically from talling on to the renewal tubes 18' disposed axially beneath them as well as in order to pre vent them from becoming damaged or from falling in, the said bobbins are received upon a deflecting plate 34 from which they slide into tube or baskets or else on to av band conveyor running along the frame.

This plate or deflector 3 4: is mounted on a hinge joint in such away that after having deflected the falling bobbins 18 it is brought back out of the path of the tubes 18 which are ascending towards the spindle plate 10. I

For this purpose the deflector 34 is pivotally mounted upon pivots 35 secured to the It comprises a bell crank,

side frames 1. lever 36 adapted to be displaced around the axis of oscillation 35 of the deflector which is controlled by means of a movable cam 37 secured to one of the carriages 26 of the rail 28 carrying the renewal tubes 18.

In the normal position the deflector occupies the position in which it deflects the full bobbins as shown in full lines in Fig. 1. When the bobbins have been removed and the rail 28 rises vertically towards the spindle plate 10, the cam 37, acting upon the le- Figure 1.

ver 36, raises it and consequently moves the deflector out of the path of the tubes 18'.

into the position shown in dotted lines in i In orderto remove the full bobbins and place the empty tubes into position the device described will operate in the following manner. t

First. The bobbins having been filled, the notched bar 21 is displaced by means of the handle 22, the effect of which is tobring the ropes 19 from the position shown in Figure 4 into that shown in Fig. 5, that is to say to move them out of the grooves .17 formed in the bases of the bobbins 18.

Second. The points of thespindles 3 are disengaged from their footsteps 15, formed in the slide plate 13, by making the spindle plate 10 descend slightly by means of the rack and pinion control 23, 24 and 25.

Third. The plate 13 is made to slide from theposition; shown in Figure 1 into that shown in Figure 5 by means of the lever 16,

the efiectjo'f which is to bring the apertures 14 in register with the apertures .11 in the spindle, plate and consequently cause the bobbins to fall on to the deflecting plate 34 from which they passiinto the baskets or on to a band conveyor.

Fourth. By means of the rack and pinion control31, 32, 33 the rail .28 carrying the tubes 18. is made to rise vertically, the deflector being at the same time moved. back, until the bases of the tubes arriveabove the planeof the spindle plate 10, slipping on to the spindles 3, the bases on the rail 28 passing through the centre of the juxtaposed apertures 11 and 14 in the spindle plate 10 and the slide plate 13.

the edges of the apertures 14 encounter the bases 30 carrying the tube 18.

Sixth. The rail 28 is made to descend by reversing the operation of the controlling members, the deflector 34 taking up its deflecting position.

Seventh. The slide plate 13 is pushed to the end of its travel so as to bring the footstep apertures 15 into alignment with the Thus for example, in the case of the application of the device to frames in which spindle spacings are small, working upon fibre and therefore fragile yarn, the fall of the bobbins on to the deflector might produce waste. In order to remove this drawback the deflector-34 is dispensed with and replaced by a collecting s stem which is brought beneath the spind e plate at the moment the full bobbins fall and comprises either tubes or small spindles upon which the said bobbins are sli )ped, the spacing between these small spindles being the same as that between the spindles 3 this spacing being if required varied by mounting the spindles upon extensiblelazy tongs or in any other way, so that the bobbins can be placed directly upon the reels without any handling capable of damaging the yarn on the bobbins.

Figure 6 shows a form of such a collecting device moving horizontally beneath the spindleplate 10. p

It consists in mounting upon the end i'rau'le'a 1, horizontal supports 38 upon which are carried the ends of a movable rail or plate 39 parallel to the spindle plate 10 and adapted to move transversel g 08 so as to come e ther into the vertical plane of the platform '10 or into an external plane parallel to the frame. 1

This horizontal reciprocating motion of the rail 39 may be obtained by any means, for example by means of racks 40 provided beneath the rail, engaging with pinions 41 keyed upon a control shaft 42 actuated from the end of the machine by a hand wheel 43.

Upon the rail are disposed small spindles 44 which are spaced the same distances apart as the spindles 3, so as to receive the bobbins 18. Fifth. The slide plate 13 is pushed untll If the spacing between the small spindles is to be capable of variation the latter are then mounted upon the centres of the pivotally mounted cross levers of a lazy tongs system disposed upon the surface of the rail 39 but any other device may naturally be employed for the same purpose.

.In the case of the application of the device to frames in which the spacings are small,

, the length of the spindles 3 may if necessary be decreased so that they do not pass outside the bases of the tubes, the effect of which shortening will be to obviate the necessity of giving the spindle plate an additional downward n'iovement, rendering consequently unnecessary the second and eight operations numerated above.
